SNOW- PLOW.

SPBCIFICATION forming part of Letters Patent No. 328,805, dated October 20,1885.

Application filed July 6, 1885. Serial Ilo. 170,749. (No model.)

To aZZ whom it may concern.-

Be it known that I, J osnrn PALMER, a citizen of the United States, and a resident of Kingsley, in the county of Plymouth and State of Iowa, have invented certain new and useful Improvements in Snow-Flows; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of a snowplow embodying my improvements. Fig. 2 is a top view of the same, with dotted lines, showing the front ends of the guard-flanges spread slightly apart. Fig. 3 isa bottom view of the same, also with dotted lines, showing the guard flanges spread slightly apart at their front ends. Fig. 4 is a longitudinal vertical sectional view; and Fig. 5 is a vertical transverse sectional view taken on the line :0 0c in Fig. 3.

Similar letters of reference indicate corresponding parts in all the figures.

This invention relates to snow-plows,or devices for clearing snow and ice and similar obstructions off railroad-tracks; and it has for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability, ease, and certainty of operation and general efficiency.

With these ends in view the invention consists in the improved construction and arrangement of parts composing the said snowplow, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A designates the platform of my improved snow-plow, which consists of an inclined plate, the front and rear ends of which are supported upon trucks B and O, which are of unequal height, the rear truck, 0, being provided with or mounted upon wheels of larger diameter than those of the front truck, thus raising the rear end of the platform to any desired height, while the front end of the platform is left raised a comparatively short distance above the rails of the track.

Secured to the upper side of the platform,

at the front end of the same, is a metallic shoe or scraper-plate, D, which may be described as forming a continuation in a forward direc tion of the said platform, and the part of which that extends in front of the forward end of the platform is supported upon strong metallic brackets E E, which are firmly bolted or otherwise secured to the frontbeam of the platform underneath the scraper-plate. The under sides of these supportingbraekets are beveled or runner-shaped, so as not to interfere with the operation of the device. The said brackets are also provided with outwardly-extending lateral flangesF F, the functions of which will be hereinafter more fully described.

Secured to the sides of the platform, at the front end of the same, are the guard-flanges G G, which consist of heavy sheet-metal plates, tapering from their rear to their front ends, where they terminate in points II, that are even with the front edge of the scraper-plate or metallic shoe D. The lower edges of the said guard-plates are provided at the front end or edge of the platform A with vertical slots or notches I, and as much of the lower edges of the guard-plates as comes in front of the front end of the platform is bent or turned inwardly,under the front end of the shoe or scraperplate, forming flanges J J, which rest upon the laterallyextending fiangesF F of the runners or brackets E E, and which in turn serve to support or to assist in supporting the projecting front end of the shoe or scraper.

By this construction and arrangement of the side guard-plates it will be seen that while their rear ends may be firmly bolted or otherwise attached to the side beams of the platform, their front ends are left unattached, so that they shall be capable of springing or yielding in an outward direction, and thus serve more effectually, not only to remove the snow and ice from the track, but also to compress it, as it were, as it ascends the platform, so that it will be certain to rise to the desired height before it drops off. By the construction shown and described all of the operating parts are also effectually braced and supported, and breakage or displacement of any of the parts, even when exposed to very severe strains, is not likely to occur.

The operation and advantages of my imthe plow progresses over the track the snow and ice will rise upon or ascend the inclined IO plane, which forms the platform of the plow,

until it passes the side guard-plates, when itwill gradually dump off the sides of the platform. The upper side of the latter may be provided with a raised triangular flange, as shown in dotted lines in Fig.2 of the drawings. Thereby the snow and ice, as it rises upon the plat form, shall be divided centrally and forced toward and over the edges or sides of the same; but I do not consider this flange an essential 2 or indispensable element of the device.

Having thus described 1nyinvention,Iclaim and desire to secure by Letters Patent of the United States 1. In a snow-plow, the combination of a platform consisting of an inclined plane mounted upon suitable trucks, the shoe or scraper-plate secured upon and extending forwardly from the same,the brackets or runners secured to the front end of the platform and extending under and supporting the proj ecting end of the shoe or scraper, and provided with outwardly-extending lateral flanges, and the side guard-plates secured to the sides of the front end of the platform, and having inturned flanges at their lower front ends, rest- 3 5 ing upon the flanges of the brackets or run ners, and serving to support the front edges of the shoe or scraper, substantially as and for the purpose herein set forth.

2. In a snow-plow,the combination of a platform consisting of an inclined plane mounted upon suitable trucks, a metallic shoe or scraper at the front end of the same, and the side guard-plates, having free or unattached front ends, provided with flanges extending 5 inwardly under the projecting front end of the shoe or scraper, the front ends of said side guards being capable of being slightly expanded by the pressure of snow and ice as it ascends the inclined plane forming the platform, substantially as and for the purpose herein shown and specified.

In testimony that I claim the foregoingas my own I have hereunto affixed my signature in presence of two witnesses.

JOSEPH PALMER.
